Abstract: A leak detector for use with a piping system, where the leak detector includes a housing configured to be attached to a conduit and a valve configured and arranged for axial movement with respect to the housing. Additionally, there is a magnet attached to the valve for movement therewith. Embodiments of the invention also preferably include a magnetically-actuated switch positioned within the leak detector along an axial flow path of a fluid such that axial movement of the magnet triggers the switch, which indicates fluid flow through the leak detector. In certain embodiments, there is also a leak passageway that permits a relatively small amount of fluid to pass to an outlet side of the valve even when a diaphragm is in seating contact with the valve if fluid pressure on the outlet side of the valve is slightly lower than fluid pressure on an inlet side of the valve.
Abstract: A dual mode flush valve includes a handle assembly having a handle, a bushing and a plunger. The bushing has a sleeve with a passage therethrough for mounting the plunger for sliding and tilting. The passage is defined by first and second partially overlapping bores that coincide at the inner end of the sleeve and are spaced one above the other at the outer end of the sleeve. The bores define a horizontal plunger travel axis and an angled plunger travel axis. Depending on which direction the user actuates the handle the plunger will travel along one of these axes. Travel along the angled axis will lower the plunger tip, allowing earlier clearance of a relief valve and a reduced flow through the flush valve compared to actuation with the plunger travel along the horizontal axis.
